cArrmc-orr DEVICE.

Application fi led ctober'18, 1922. Serial No. 595,293.

To all whom it may concern Be it known that I, Gus l/V. SwANsoN, a citizen of the United States, residing at Morgantown, in the county of Monongalia v and State of West Virginia, have invented a new and useful Capping-Off Device, of which the following is aspecification.

This'invention is a device for capping-off glass cylinders, and for cutting such cylinders into flattening lengths incidental to the manufacture of window glass. Y

One of the objects of the invention is to V produce simple means whereby an electric heating wire may be utiliz'ed for applying the cracking tension to the glass. A further object is to provide a device of the character mentioned, which may be adjusted to cylinders of different diameters. A further object is to provide means whereby the heating wire may besnugly drawn around the cylinderto' be operated on, and held in position to secure the cracking tension, its ends being so positioned as to insure a small gap which will prevent short circuiting of the,

2 wire. A further object is to provide a device in which the horse normally employed to support the cylinder during the cappingofl' and crackingoff? operations,vmay be utilized to support the line wires and contacts complemental to the contacts of the heating wire. i

The invention will be hereinafter fully set forth and particularly pointed out in the claims. e In the accompanying drawing 7 Figure 1 is a top plan view of a horse with a capping-01f device constructed in accordance with the invention applied thereto. Figure 2 is an end view. thereof. Figures inder-supporting arms 15, the inner ends of which are engaged by the longitudinally disposed anchoring bar 11. The last mentioned bar is T-sha-pe in cross section, and

3 and 4 are detail cross sectional views illustrating arrangements of line wire and con-c with telescopingrods 14, which engage cylis connected to thebar 10 by uprights 16. The construction thus far described is a Well-known type of horse, commonly. em-

ployed in window glass factories for sup porting glass cylinders during the cappingoff and cutting operations, and is disclosed herein solely for illustrative purposes.

Secured to the bar 11 are a plurality of laterally extended brackets 17, which support longitudinally disposed conduit bars I 18, provided with longitudinally disposed open grooves 19 and 20, in which are located line wires 21 and 22 respectively, which may be connected in any desired-manner (not shown), with suitable source of electrical energy. Secured tothe top of each bar 18 are a plurality of contact plates 23, said plates being separated by spaces conforming approximately to the normal flattening lengths into which a cylinder is usually cut. Said plates are electrically connected in suitable manner' with the line wire 19, and are provided with a plurality of upstanding contact pins 24.. Extending across each contact plate 23 and insulated therefrom is a contact socket 25, which is electrically connected in suitable manner with the wire 20. The

arrangement of the contact plates 23 and the I sockets 25 is such that a circuit wire having one end connected toany one of the pins 2a and the other end connected with the socket 25 will place the wires 21 and 22 in circuit.

The capping-off device per se, comprises a switch 30, mounted upon an insulating base 31, said base being provided with a socket 32, into which is inserted one end ofacontact member 33, which is secured in position by means of the binding screw 34:, whereby said contact member 33 is connected with one 'terminalof the'switch 30. Said contact member. is also enclosed within an insulating sleeve 34', which is somewhat'shorter than the contact member so astoalloW a 7 small portion of the latter to project. To the projecting end of the contact member 33 is connected one end of the heating wire 34:, the other end of said wire being connected with one end of acontact member35, enclosed within an insulating sleeve 36. The other end of said contact member 35 projects beyond the sleeve .36 and is bent to form an eye 37. The other terminal of switch ,30 is connected. by a flexiblewire 38,

with another contact member 39, extending through an insulating sleeve 40, one end of said contact member projecting beyond the sleeve and being split as indicated at In practice, the cylinder is first taken down and placed upon the arms 15 ot' the horse in a manner well-understood in the art. hen it is desired to out the cylinder into lengths, the operator holds the switch member 31 and its attached insulating member 3% in one hand, and with the other drops the insulating sleeve 36 and its enclosed contact member 35 back of the cylinder. He. then reaches under the latter and grasps the sleeve 36, pulling it forward and up over the glass, finally hooking the eye 3'? over any one of the pins 24-. He then pulls upon the switch member 31 drawing the wire 34" tightly around the cylinder, after which the split end ll 01' the contact 39 is inserted into the socket 25, the crossing portions oi? the wire 34 lying close together but not in contact. He is then ready to turn on the current by means of the switch 30, and the capping and cracking oil operations are carried out in a manner well-known to those skilled in the art.

The advantages of the invention will be readily apparent to those skilled in the art to which it appertains. It will be particularly noted that an electrically heated wire is conveniently used for the capping-oft and cracking-of? operations. and that the parts are so arranged that the wire may be readily drawn around cylinders of different sizes. A further advantage lies in the fact that the ends of the wire 34 may be brought close together so as to insure a very small gap, which will prevent short circuiting of the wire, and at the same time insure a substantially even cut around the cylinder along the line of cracking tension. By placing the line wires and contacts upon the horse which supports the cylinder. a very convenient arrangement is provided by which the various operations are greatly facilitated.
